Are things really that bad?
Purdue is 17-4. It has lost twice to a team currently in the top 10 and is one of the hottest teams in America. Both times it led that team at halftime only to be undone by a bad second half. The first time was much more disastrous than the second (because blowing a 17 point halftime lead at home is bad against anyone), but still, it is clear Iowa is a very good team and in the driver's seat to win the Big Ten.
The other two losses are to a good, but not great Butler team and an Illinois team that is bad, but played out of its mind for 40 minutes.
